3.3

The initial loading process became more efficient and up to 45% faster.

Memory usage during the fusion process has been reduced for up to 60%.

Full scan batch queries performance has been increased for queries with a big number (several thousands or more) of non-key parameters.

Http interface for old data removal has been improved.

The new version supports JMX technology, which allows easy Equator Server monitoring.

Logging information became more structured and informative.

Http interface for old data removal has been introduced.

3.2

Internal parallelism has been improved:

Full scan queries can now be parallelized on block level for each sharded/sstable file.

Loading from compressed files has been implemented:

Data can now be loaded from gzip/snappy compressed files. The algorithm is automatically detected based on file extension.

Http interface for old data removal has been introduced.

3.1

Virtual fields feature has been introduced:

This feature allows to specify a virtual field in table schema as a operation (e.g. sum), applied to regular table fields. The virtual field can be then used in "collectMinMax" schema section and in the query conditions.

List queries feature has been introduced:

For any one field in the search conditions a list of values can be specified instead of a single value.

3.0

Equator Server is the new generation CopperEye product:

Designed to satisfy the need of telecommunication providers for big data retention, Equator makes it possible to query petabytes in seconds.

Two storage engines are introduced - sstable and sharded:

Those engines utilize modern approaches to data warehousing without using indexes and make it possible to find an optimal balance between query performance and storage density. Such technologies as partitioning, binary data representation,intelligent compression and bloom filters are also used.

Faster search and loading, denser storage:

Equator queries are up to 100 times faster than those in Greenwich, data is loaded up to 10 times faster and utilizes up to 6 times less disk space.

Convenient interfaces:

HTTP JSON and JDBC APIs are implemented for easy integration with third party applications.

Data Acquisition Bus:

A modern replacement to CopperEye CSync is introduced, designed to validate, transform and deliver data to Equator cluster.
